So, I have a problem when the player joins the server, it does not update the tab name for the player that is set. The basics in the plugin (code) are all right. I can not send a screenshot because it would not be valid because it is a PlayerJoinEvent.
Here is the code from PlayerJoinEvent:

	@EventHandler
	public void onPlJoin(PlayerJoinEvent event) {
                // This is just a random name choice.
		event.getPlayer().setPlayerListName("Name");
        }

And so it does not work. I can only get the name from a scheduler.
